Over-voltage Study of 500 kV Transmission Lines in Black-start of Power Grid |
| |
| Abstract: | This paper presents the study on problem of over-voltage in the black-start path which consists of Hebei Southern Power Grid 500 kV transmission line.Based on MATLAB/Simulink and PSCAD/EMTDC,calculates and analyzes the unload over-voltages.The results show the feasibility to switch on unloaded lines in the Hebei Southern Power Grid and are useful for making the black-start schemes of Hebei Southern Power Grid. |
